Delivery can be by cable, satellite, DVD, digital, terrestrial or computer onto various types of screen.

Plasma Larger (from 42" diagonal) flat screen can take input from any visual source e.g. TV, DVD, digital etc. Half-life, i.e. fades to half of initial resolution, after 25,000 hours (assumed industry average)

LCD Double the half-life and generally require less maintenance and service than plasma. Becoming available in larger sizes (15 - 36" is usual) at more affordable prices.

CRT Your traditional TV, now less commonly available because of improvements in plasma and LCD, which both have flat screens giving greater viewing distance than the curved screens of CRT.

Projection For images around 4 - 10ft in large communal spaces where screen is required to be less obtrusive when not in use and can be dropped electrically e.g. lounges, pubs, spinning classes.
